Bugs: AMBARI-19907
https://issues.apache.org/jira/browse/AMBARI-19907
Repository: ambari
Description
-------
On a big cluster, it takes the server a long time to process the API request
for certain operations, like "Stop All", "Start All", etc.
On a small cluster, the "background operations" popup appears within a few
seconds to acknowledge to the user that the server is working on handling the
request.
However, when the cluster gets bigger and the request API takes the server much
longer (e.g., on a 1000-node cluster, it took ~35 seconds), there's no
indication on the UI that the server received the request. This is not
reassuring to the user and the user is tempted to keep re-triggering the action
and overwhelming the server.
This problem is not just for "Start All", "Stop All". This problem actually
happens for "Stop" and "Start" of a single service as well (and likely other
places, like Hosts / Host Detail pages.) On the 1000-node cluster, this takes
about 6-7 seconds, enough to make the user wonder if the request got to the
server or not.
